'rentrer FOR' oi Specification of Letters Patent.

Patented Nov. 27, 1906.

Application filed April 9, 1906'. Serial No 310,762.

Be it known that l, limitan, t'oin'ux, a citizen of the United States ol' rxmeriea. residing at Holyoke, in the county oll liampden and. State ot Massachusetts, have invented new and useful Improvements in Trolleys if'or Overhead Tracks, ot' whieh the following is a specification.

This invention relates to the class ol eardoor hangers, and has 'for its object to pro-v 'vide a structure that is simple in const-ruetion and one that is economical to manufacture.

BroadlyI the invention consists in making the track that supports the carrier serve the double purpose ot track and wea-ther protector; a1'1d,'lurther',it consists in making the carrier (on which the carrier-wheels are supported at its opposite ends) with a ytransverse depression about midway of its length and pivotally securing in this depression a hanger with an otl'set for the purpose oll bringingl the door into close sliding relation with the side of the car. Y'

in the drawings forming part ot this applioat-ion7 Figure l is a side elevation ol' my improvement. Fig. f2 is a Vertical seetion on the line 'l 2 oi Fig. l. Fig. I is a detail plan View showing the transverse depression in the. carrier-bar and also showing the pivotal connection between the hanger-bar and thel carrier-bar. l

Referring tothe drawings in detail. u designates a portion of the framework ol the ear.

b designates the usual longitudinal supporting-piece t'or the trolley-track e.

d designates a scouring-bolt' passing through a hole drilled in the upper edge ot the track c and also through the longitudinal supporting-piece on the framework (t ol" the car ior rigidly securing these parts to the var.

It will be noticed that the` trolley-track is 'made with a straight portion 'for the greater part ot' its widthJ while the lower part ot' the t saine (on which the trolley-wheels run) is` bent or rolled into the torni of a curve, as j olI the ear, or, in other words. the trac longitiuliually ot the track and farries at its opposite endsl the trolley-wheels g, which are adapted to rotate freely on the iiXed pivots or pins It. It', will be noticed that this carrier-hanfhas an oltset portion transversely otl its length A(as Clearly shown at i, in. Fig 3) which is formed substantially midway ot the length of the carrier-bar.

j designates the pendant or door-hanger iron, to which the door ,lt- .is secured by .means ot the bolts` ym in the usual manner. This hanger-iron is proi'ided with a transverse oil'- set. (shown at n) and. is pivotally secured to the carrier-inn' j" b y a pivot-pin 0 in the transverse depression i ot the carrier-bar.

The purpose ol:- t'orming a transverse otl'set in the carrier-bar is lor bringing the tread ol the trolley-wheels (7 in Vertical alinenienvt. with the lowermost part ot" the curve of the trolley-track u, and by having an otlset in the hanger-iron j, to which the door is attached, the car-door being thereby broughtl into elose relation to the side ot' the Car.

it will be seen that by making the trolleytrar'k in the torni shown the saine serves the double. purpose ot' a trolley-traek and weather-protecting pieve tor the carrier-bar and troller-wheels and prevents any rain or snow trom gaining admission to the interior k e dispenses with the use ot: a weather-strip, which is absolutely necessary to protect the opi-rativo parts in many ot' the overhead Carrier devices now on the market,

li'aving thus described my invention, what i claim, and desire to secure by Letters Patentol' the United States, is

l. in .an overhead carrier meclianisinfa trark having a. curved tread, a. carrier-bar haring a transverse. otlset substantially in itin: middle portion otl its length, trolleywheels rotat'ively supported by the carrierbarvv a pendant or hanger-bar pivotally secured io the earlier-bar and in th(` ollset portion tin-reol', and having an ollset therein whereby the iVolley-wheels will be located ill the eri ical plane ut' the earrier-bar, and `the V rar-door will be brought in `close sliding relation with ,the side oti the ear` and means l'or supporting the traek.

L. A trolloy-rai'rlcr comprising two trolleywheels, a damier-bar near the o )posits ends of which the Wheels are rota-Livey supported in the same plano, said bar having a, transverse depression thereon about nndwzyy bc- Lween its ends; a. pendant for the carrier-bar pvotall secured thereto in said depression, on Whio pendanta door or the like may be suspended, tho ond of said pendant at thc point of its attachment to the bm being off-- sot in the direction of tho carrier-bar.
